DIY Dust Filtration Box





Introduction: DIY Dust Filtration Box

I have a lot of dust in my little basement wood shop. New off-the-shelf ceiling mounted filtration units are a bit expensive. So before buying one I did an easy little build using an old window fan and some scrap wood that was laying around. So far I've been pleasantly impressed. It moves a good amount of air, is very quiet, and doesn't take up a lot of room. Time will tell just how efficient it is, but for now it seems okay.

For the filtration I used two cheap blue filters 12" x 24" x 1", and then one good 3M filter of the same size. I wired in a switch and screwed the box to the ceiling joists.

The video shows the full build. The whole project only took a few hours.

Thanks for taking a look.

Awesome! I'd be curious as to how much dust will end up getting stuck inside the fan even after it passes through the filter like that. That's an excellent diy filter!

This looks really great, and has gone on my "To Build in the Near Future" list! Great job making it yourself - the cover looks superb.
